WASHINGTON — The Treasury Department said it will sell 1.5 billion shares of Citigroup stock over the next two months, the latest effort to recoup money from the government’s $700 billion financial bailout.

The third phase of Citigroup stock sales will begin immediately and end by Sept. 30, Treasury officials said Friday. The government already has sold 2.6 billion shares for $10.5 billion.

250 people -- all homeless and high-frequency users of jail, detox and emergency departments at taxpayer expense -- have been tracked down by Colorado Coalition for the Homeless and Mental Health Center of Denver outreach workers and given apartments through Denver's social-impact bond program.
